Last week I've bought AP TL-WA801ND, that don't work in my specific condition with stock firmware. Because on this site (and on dd-wrt site too) there is no support page for this AP, I tried to flash the firmware for similar AP/router.

My AP hardware version is "Ver:1.1". PCB is similar to tl-wa901nd one. So I've soldered 4-pin connector and tried to flash openwrt.

The procedure was standard for TP-LINK:

The openwrt I've tried don't work correctly:
wr841nd (ver 5): can't connect by ethernet
wa901nd: wifi don't work
May be it's my problem, may be openwrt really don't support this AP.

But dd-wrt (for wa901nd) works without any problem (ethernet and wireless work both).
So if someone want to add support for openwrt/wa801nd the questions welcome.

Hi,

Can you tell us the chip number under the heatsink? (i think it's Atheros)

How much Flash & Ram does it have?
Read on the Flash & Ram chips and post thier numbers here.

I have track down it's FCC ID number:
FCC ID = 'TE7WA801ND'

Very interesting router for Bridging long range, it has 20dBi (100mW) RF output power!!!

I like to buy 2 piece of them to make a decent Bridge.

All information is welcome!

Vaako

I don't have this router now. But compare my PCB photo and TL-WA901ND's PCB photo. It's the same (the difference is the antenna switch). So we can think the components are the same. Anyway exact information wil be in a week.

4M flash (Winbond 25q32bvs1g-? )
32M ram (Zentel A3S56D40FTP)

if you are interesting with radio module see this photo from our colleagues.

Regards.

Thank you for the information!!!

Do you now what Atheros CPU is used?

Wireless chipset Atheros AR9238-AL1A
4mb Flash (Winbond 25Q32BVS1G)
32mb Ram (Zentel A3S56D40FTP)

I can't find anything about the U5 and U6 chip the MSC5511 Amplifier, no datasheet available.

not yet

LX5511

Maybe it's ar7241,I saw someone flash a mr3420 with wa801nd's fireware and works fine.

NO! It glued perfectly. but:

@pn2k3

Thank you for this information, do you have connect a serial JTAG or Telnet, SSH to the TL-WA801ND ???

Could someone make some inside fotos ?

would like to know which kind of switch is build in.

You can see PCB photo in my first post. And I think nobody installs switch ICs in APs, only in routers.

radio wa901nd built on a chip Atheros AR9285, and wa801nd has a chip Atheros AR9283. I think so does not work wifi.

wr841nd has 4 ports and wa801nd - one port.
look closely:

trunk \ target \ linux \ ar71xx \ base-files \ etc \ defconfig \ tl-wr841n-v1\network

config interface eth
    option ifname    eth0
    option proto    none

config interface lan
    option ifname    "lan1 lan2 lan3 lan4"
    option type    bridge
    option proto    static
    option ipaddr    192.168.1.1
    option netmask    255.255.255.0

config interface wan
    option ifname    wan
    option proto    dhcp

and trunk \ target \ linux \ ar71xx \ base-files \ etc \ defconfig \ tl-wa901nd\network

config interface eth
    option ifname    eth0
    option proto    none

config interface lan
    option ifname    lan
    option type    bridge
    option proto    static
    option ipaddr    192.168.1.1
    option netmask    255.255.255.0

replace it?

Why is this repeater still not officialy supported ?
Does image from tl-wr841n-v1 work with the changes to network config ?

Mark,thanks. 20dbm of MSC5511 in 54g, 18dbm in 11n.
tp-link wr941n v2 use this PA in there streams.
Any other routers? Linksys wrt120n uses MSC5511 too, any others?

Hi all, question about how to correct install open WRT on this devise... have V2.
i nstalled - openwrt-15.05-ar71xx-generic-tl-wa801nd-v2-squashfs-factory.bin - all ok, now device have openwrt FW.
but what about - openwrt-15.05-ar71xx-generic-tl-wa801nd-v2-squashfs-sysupgrade.bin - what is it? and how i can upgrade - and for what this file? i alredy try to install it via Web gui via firmaware tab, but nothing changes.
in this devise i only need 802.1x (eap-peap-mschapv2) autirization via WISP.
thanks!
